But if it is limiting the stack a lot, then that might be it. dwarf_getsrclines () uses some alloca () calls for temporary memory. [...] The NEW_LINE define uses alloca. Try the same stap command without the -rlimit-stack=... arguments to see if that is it.

Java method probing support using Byteman, stapdyn -G global variable support, misc stapdyn bugfixes &amp; internal improvements = Where to get it http://sourceware.org/systemtap/ - our project page http://sourceware.org/systemtap/ftp/releases/systemtap-2.2.1.tar.gz http://koji.fedoraproject.org/koji/packageinfo?packageID=615 git tag release-2.2.1 (commit 9c4e07c8a3) There have been over 200 commits since the last release. There have been over 30 bugs/features fixed since the last release. = How to build it See the README and NEWS files at http://sourceware.org/git/?p=systemtap.git;a=tree Further information at http://sourceware.org/systemtap/wiki/ = Systemtap frontend (stap) changes - Basic support has been added for probing Java methods using Byteman http://www.jboss.org/byteman as a backend. Java method probes can target method entries, returns, or specific statements in the method as specified by line number. They perform much better than the hotspot.method_** probes that instrument all-or-none of the entire java app. probe java("org.my.MyApp").class("^java.lang.Object").method("foo(int)") { println($$parms) } See java/README for information on manual setup for Java/Byteman functionality. Set env STAPBM_VERBOSE=yes for more tracing. - A systemd service file and tmpfile have been added to allow systemtap-server to be managed natively by systemd. = Systemtap runtime changes - The dyninst backend has improved in several aspects: - Setting custom values for global variables is now supported, both with -G when compiling a script, and from the stapdyn command line when loading a precompiled module. - A transport layer has been added for two-way communication between the stap process and the target process. For now, this allows systemtap output to be correctly printed to the stdout of the stap process, rather than the target's stdout. = Systemtap tapset changes - Due to the removal of register_timer_hook in recent kernels, the behaviour of timer.profile has been changed slightly. This probe is now an alias which uses the old mechanism where possible, but falls back to perf.sw.cpu_clock when the kernel timer hook is not available. To require the kernel timer hook mechanism in your script, use timer.profile.tick instead of timer.profile. - New tapsets: timers.stp defines timer.profile probe alias - Changed tapsets: nfsd.stp add uid, gid convenience variables to nfsd.proc.* in nfsd.proc4.write, set vlen to 0 if wr_vlen doesn't exist syscalls2.stp add syscall.sendmmsg and syscall.sendmmsg.return nd_syscalls2.stp ditto task_time.stp add cputime_to_usecs() and usecs_to_string() - The following tapset variables are deprecated in release 2.2: - The 'origin' variables in the 'generic.fop.llseek', 'generic.fop.llseek.return', and 'nfs.fop.llseek' probes. The 'origin' variable has been replaced by the 'whence' variable. - The 'page_index' variable in the 'vfs.block_sync_page' and 'vfs.buffer_migrate_page' probe aliases. - The 'write_from' and 'write_upto' variables in the '_vfs.block_prepare_write' and '_vfs.block_prepare_write.return' probe aliases. - The 'regs' variable in the 'syscall.sigaltstack', 'nd_syscall.sigaltstack', 'syscall.fork', and 'nd_syscall.fork' probe aliases. - The 'first', 'second', 'third', and 'uptr_uaddr' variables in the 'syscall.compat_sys_shmat' and 'nd_syscall.compat_sys_shmat' probe aliases. - The following tapset functions are deprecated in release 2.2: 'ppos_pos', '_dev_minor', and '_dev_major' - The following tapset functions used to return error strings instead of raising an error. The original behavior is deprecated in release 2.2. 'ctime', 'probemod', 'modname' = Systemtap sample scripts - New samples: eatmydata.stp - (guru mode) suppress fsync() syscalls in indicated process - Changed samples: hw_watch_addr.stp use a more-likely-to-trigger target symbol hw_watch_sym.stp ditto iodevstats.stp switch from _dev_minor and _dev_major to MINOR and MAJOR mutex_contention.stp drop compulsory array-size argument = Examples of tested kernel versions 3.10-rc1 (i686, x86_64) 3.9.0 (x86_64) 3.8.11 (armv7l) 3.5.0 (i686) 3.4.0 (armv7l) 2.6.18 (i686, x86_64) 2.6.9 (i686) = Known issues with this release - Some kernel crashes continue to be reported when a script probes broad kernel function wildcards. (PR2725) - The java byteman backend is a work in progress. Robustness issues are suspected with concurrent user and/or JVM usage, and some installation steps are manual. Not enough context variables are available. But it's a start! - The dyninst backend is still a work in progress. Current issues: + lack of support for multiarch/cross-instrumentation + tapset functions are still incomplete relative to what is supported when the kernel backend is active + exception handling becomes completely broken in programs instrumented by the current version of dyninst (PR14702) + command line interrupts are slightly mishandled (PR15049) + not all registers are made available on 32-bit x86 (PR15136) See dyninst/README and the systemtap/dyninst Bugzilla component (http://tinyurl.com/stapdyn-PR-list) if you want all the gory details about the state of the feature. = Contributors for this release Dave Brolley, David Smith, Frank Ch.

I asked the release team to consider accepting version 1.7-1+deb7u1 that fixes the issue to debian wheezy as a proposed upload: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=708243 If you run systemtap on debian wheezy I'd like to hear from you, do the packages at http://lindi.iki.fi/lindi/systemtap/wheezy/ work fine for you?

When we are trying to find a type DIE we might hit upon a DIE that simply has a DW_AT_signature pointing to the actual type (possibly in .debug_type). Extend the debugtypes.exp testcase a bit. Add DW_AT_signature chasing to dwarf_wrappers.h (dwarf_attr_die) when searching for a DW_AT_type. And clarify that dwflpp::print_members takes a type DIE not a variable DIE. </pre> mjw at redhat dot com 2013-05-15T16:01:27 Search Engine Search the mailing list at Gmane query http://search.gmane.org/?group=$group=gmane.linux.systemtap
